Help! Trying to fix, but where to start?

Little update. Installed a adjustable gas block from MidwayUSA, and a Mo-Rod from Sunflowerammo. I can now easily pick up my brass now from 5ft away (not 40). It shot vertical strings of about 14" at 100yds prior. Now I'm getting about 2" GROUPS at 100. Very excited. I'll start handloading to fine tune. Sure is nice to have a gun that shoots now. Thanks again to everybody for their inputs and advice.
